The study of a planar G-band extended interaction oscillator (EIO) driven by a pseudospark-sourced (PS) sheet electron beam is presented. This enables the advantages of a planar interaction circuit combined with the merits of a PS sheet electron beam, including large beam cross section, high current density and the fact that a PS electron beam does not require the use of an external focusing magnetic field. Beam-wave interaction simulations for this planar EIO predicted a peak output power of 2.1 kW at ~0.2 THz. Investigations indicate that this planar EIO has a better tube performance with a higher radiation power compared with the PS pencil electron beam EIO.
